- the word “unitary” means a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a “unitary” component or body.
- the statement that two or more parts or components “engage” one another shall mean that the parts exert a force against one another either directly or through one or more intermediate parts or components.
- the term “number” shall mean one or an integer greater than one (i.e., a plurality).
- fastener and “attachment mechanism” refer to any known or suitable securing mechanisms for securing one part to another part, and expressly include, but are not limited to mechanical mechanisms, Velcro, snaps and adhesives.
- number shall mean one or an integer greater than one (i.e., a plurality).
- FIGS. 1-3 illustrate an exemplary embodiment of a patient interface device 10 (also referred to as a gas delivery mask) according to the principles to the present invention.
- Patient interface device 10 functions to communicate a flow of breathing gas between a patient's airway and a pressure generating device 12 (shown schematically), such as a ventilator, CPAP device, autotitrating CPAP device, PPAP, PAV®, or variable pressure device, e.g. a BiPAP® device manufactured and distributed by Phillips Respironics, Inc. of Pittsburgh, Pa., in which the pressure provided to the patient varies with the patient's respiratory cycle so that a higher pressure is delivered during inspiration than during expiration.
- Patient interface device 10 in the form of a gas delivery mask for delivering a flow of gas to an airway of a patient.
- Patient interface device 10 includes a mask shell 14 or body portion, which is preferably, but not necessarily, a generally rigid, formed structural shell having an open side that defines an annular portion 16 to which a resilient, relatively soft cushion or seal member 18 is attached.
- mask shell 14 is substantially triangular in shape, having an upper apex angle 20 and two lower angles 22 .
- Mask shell 14 includes an inlet opening 24 adapted to receive a gas supply conduit 26 (shown schematically).
- gas supply conduit 26 shown schematically.
- mask shell 14 is formed from rigid plastic, such as Polycarbonate.
- Seal member 18 is configured to receive a portion of the patient, such as the nose.
- FIGS. 1-3 is a typical nasal mask. It is to be appreciated that the present invention can be used on any patient interface device either nasal, oral, oral-nasal or nasal cannula system, as long as the mask employs a separate support or supports that contact any part of the face other than the sealing area. It is to further be appreciated that although the exemplary embodiment shown in the figures is a forehead pad piece, which is conventionally placed above the cushion (sealing element) on the forehead of a patient, the present invention may be employed with other external supports (e.g., without limitation, cheek pads).
- a lower headgear connector assembly 28 includes a pair of first connectors 30 rigidly attached to lower angles 22 of mask shell 14 .
- Lower headgear straps (not shown) in headgear assembly are selectively connected to mask 10 by means of a second connector 32 .
- a pair of second connectors 32 are removably connectable to end portions of headgear straps (not shown) and are also removably connectable to first connectors 30 on each side of mask shell 14 .
- lower headgear connector assembly 28 can be any suitable headgear connector assembly.
- the headgear can be any suitable headgear, i.e., any conventional headgear used in the patient interface field.
- a typical headgear assembly comprises a headpiece (not shown) that overlies a portion of the patient's crania and with a pair of lower headgear straps and a pair of upper headgear straps extending therefrom to adjustably connect the headgear to the mask.
- a forehead support 34 is provided at upper apex angle 20 .
- Forehead support 34 in this embodiment is generally T-shaped and includes a support arm 36 , which is connected at its upper end 38 ( FIG. 2 ) to a horizontal forehead support bracket 40 .
- Forehead support bracket 40 includes a forehead pad assembly 50 ( FIGS. 2 and 3 ) on the patient contacting side which is discussed in further detail below.
- Each end portion 42 of forehead support bracket 40 may include a connector element 44 for securing an upper headgear strap 46 .
- connector element 44 is a female receiving slot for receiving a male quick release element 48 attached to an upper headgear strap 46 .
- other connection mechanisms could be used.
- Pad assembly 50 forms the actual contact point of forehead support bracket 40 to the forehead of the patient (shown in phantom line in FIG. 2 ) and includes an outer casing 52 and a support element 54 .
- Outer casing 52 has a generally hollow springy structure preferably formed from a rubbery material such as silicone or thermoplastic elastomer (TPE) or other suitable material, which is preferably substantially impermeable to moisture. In this manner, outer casing 52 will be relatively easy to wipe clean, and will also function to prevent the undesired entry of moisture into support element 54 contained therein, as will be described below.
- TPE thermoplastic elastomer
- outer casing 52 was molded in a silicone rubber with hardness about 20 to 40 Shore A with a wall thickness from about 0.75 millimeters to about 1.5 millimeters.
- outer casing 52 includes a mounting portion 56 and a housing portion 58 .
- Mounting portion 56 is of slightly curved shape and includes a first side 60 , an opposite second side 62 and an opening 64 passing therebetween.
- a number of coupling mechanisms 66 extend from first side 60 of mounting portion 56 for use in coupling pad assembly 50 to forehead support bracket 40 .
- coupling mechanisms 66 comprise protrusions that are connectable to respective openings (not illustrated) on forehead support bracket 40 .
- housing portion 58 is formed from a slightly curved first wall 68 structured to contact the patient and a second wall 70 , generally curved a greater amount than first wall 68 .
- Second wall 70 is coupled to second side 62 thus coupling housing portion 58 and mounting portion 56 together.
- mounting portion 56 and housing portion 58 are formed as a unitary member, however it is to be appreciated that mounting portion 56 and housing portion 58 could be formed separately without varying from the scope of the present invention.
- First wall 68 and second wall 70 of housing portion 58 generally define a cavity 72 therebetween, as shown in hidden line drawing in FIG. 5 .
- FIGS. 7 and 8 show an exemplary support element 54 according to an embodiment of the invention in which support element 54 is custom formed from a “closed” cell skinned foam material, such as a silicone-foam material formed to cooperatively fit within cavity 72 of housing portion 58 of outer casing 52 , as shown by phantom line in the pad assembly 50 of FIG. 9 .
- the flexible nature of outer casing 52 and support element 54 allow for the insertion of support element 54 into outer casing 52 via opening 64 . Once installed, outer casing 52 substantially surrounds support element 54 .
- a silicone-foam material having a density (pcf) of about 14.5, a softness (Shore 000) of about 20-25, and an average cell size (mm in diameter) of about 0.5 (fairly uniform ranging from about 0.2 to 0.8) in open cell structure, has been employed.
- a polyurethane foam either Ester or Ether having a density (pcf) of about 8.5, a softness (Shore 000) of about 20-25, and an average cell size (mm in diameter) of about 0.5 (fairly uniform ranging from about 0.2 to 0.8) in open cell structure, has been employed.
- support element 54 may also be formed from an “open” cell soft foam material such as, for example without limitation, any non structural foam with compression and expansion capability, typical materials are Polystyrene and Polyurethane.
- Such “open” cell foam material may be die cut, such as shown by support element 54 ′ of FIG. 10 .
- such “open” cell material may be suitably formed to have a desired shape, such as, for example without limitation, the shape of support element 54 of FIGS. 7-9 .
- the rather soft nature of support element 54 ′ will generally result in support element 54 ′ contouring to the shape of cavity 72 as shown in phantom line in the pad assembly 50 ′ of FIG. 11 .
- support element 54 may also be formed from any suitable resilient cushioning material, and may include, for example and without limitation, more than one element and/or different sizes or variations of elements formed from alternative materials, such as gel, foam, silicone, or viscoelastic foam or memory foam. Additionally, the selection of the particular material employed as support element 54 or, at minimum, particular attributes of the material, may be left up to the end user (patient) to allow for custom tailoring of the pad assembly 50 by the patient. In such instances, a number of different types of interchangeable support elements 54 would be supplied from which the patient could pick and choose as desired.
